Arrowhead/indian artifacts collection

I put my collection in this shadow box, some I found some were my father's and the rest were purchased. Not sure where the ones I bought were found S there wasn't any information with them. Some are from the Texas panhandle and some from the Sierra mountains in California. The bone is a piece I found that I'm pretty sure is an awl/scraper, fits perfectly in my hand either direction. It is fossilized and I'm thinking possibly deer femur.
